Four cube faces cover front, right, back and left, one the [[Zenith]] and one the [[Nadir]], each of them having 90�x90� [[field of view]]. In each cube face all straight lines stay straight, hence it is very good for editing.

Images in the Cubic projection are commonly used as the image source by several spherical [[Panorama Viewers|panorama viewers]], including [[SPi-V]] and [[Quicktime]].

Cubic is a type of projection for mapping a portion of the surface of a sphere (or the whole sphere) to flat images. The images are arranged like the faces of a cube and are each one in the Rectilinear Projection. This cube is viewed from it's center.
